Application filed November 6, 1920. VSerial No. 422,329.

To all whom fimay concer/n.' n H Be it known that I, GEORGE A. SETE,c1ti- Zen of the United States, and resident of Ilion, in the county ofHerkimer and State of New York, have Vinvented certain new and usefulImprovements in Typewriting-Machines, of which the following is aspecifica-,l tion.

My present invention relates to paper feeding mechanism for typewritingmal chines and'its object generally stated is to providenew andrimproved mechanism of the character specified. More specifically theobject of theV invention is to provide means for kfacilitating theadjustment of a plurality of work sheets So that they may be accuratelyalined relatively to vthe printingV point or line and independently ofeach other.

To the alcove and other ends which will. -hereinafter appear, my presentinvention consists in the features of construction, co1nl binations ofdevices and arrangements of parts hereinafter described and particularlypointed out in the claims.y Y A v y In the accompanying drawing whichillustrates one form of the invention,

Figure 1 isa fragmentary vertical sectional view showing the upperportion of a No. 11 Remington type-writing machine embodying myinvention, the section being takenk on planes indicated by the brokendotted yline ca in Fig..2 and looking in i' the direction of the arrowat said line.

Figs. 2 and 3v are respectively right-hand and left-handV Vportions of atwo-part or divided platen shown in vertical longitudinal section.

Fig. ais a vertical sectional viewy taken on a plane indicatedby thedottedvyline g/-y in Fig. 1 and looking forward. Y

Fig. 5 isa perspective view of a detail.

Referring to Figs. 1, 2 and 3, the main frame of the' machine includes atop plate 1 above which are secured lugs 2 on which are supportedgrooved guide rails, as 3, that coperate through antiffriction rolls 4with the front and rear bars ofia carriagetruck, only the rearV bar 5being shown, said truck further including end bars 6v connecting saidfront and rear bars." Shiftably connected with said carriage truckybyvdevicesv 7 is a platen frame or carrier comprising end bars or plates8 and cross Irods or bars 9 .wel l0, said .platen frame together Wlththe supporting truck constituting a travel-V Specification of LettersPatent. i -Patente'd Oct. 4 192.1.YL

platen, cooperative with Athe front face` f ywhereof is'a combined lineindicator and guide 14 that is mounted on the'platen shift-` ing frameof the machine and isvprovided. with an edge or face 15 that registerswith or is opposlte to the printing line on the splitV cylinder ortwo-part platen, the two partsV being equal in outside diameter.. Thelefthand platen section o r. element 16v ofl saidV two-part laten isarranged co-axially with' lthe ri lhtandsection or element 1'(l thereofand t ese parts or elements maybe consid- Vered as platens inthemselves, they being adapted to accommodate separate work sheets. Theleft-hand platen orsection 16 comprises. a core 18 of .woody and asheathvv 19- ofrubber and has Secured toits lefthand end a laten head20. Said platen head 1s suitab y secured to the interior of a -metaltube or core 23 thatis driven into or otherwise secured'in the bore ofthe wooden core 18, a dowel pin 24 connectin said head l.

2O with the core 18. Said head ts over theV shaft` 11 and has anoutwardly projecting` hub which receives a screw 25 which abuts againstthe shaft 11 and secures it inffixed relationship withv theY head 20.and the platen or section 16. The shaft 11 bears in a flange or sleeve26 that is screwed through an opening in the left-hand end bar '8 and isYlocked in place thereon by a check nut 27. A washer28 is interposedbetween the sleeve 26.*and the hub of the i platen head 20 to assist inmaintaining the platen section 16 properly spaced from the end of theplaten frame, The core or sleeve 23 extends rightward beyond the platen16 y and is provided at its .right-hand end with inturned ears 29 whichreceive screws 30 whereby the sleeve 23 and the platen section 16 areconnected` with platen clutch devices for releasably connectingthcplaten section 16 .with its line spacing ratchet wheel 31.l Theplaten clutch devices are preferablyof the construction employed in theNo.1'11 Remington. typewritmg. machine and lare substantially asdisclosed inthe .patent to Woodward'945,358,granted January 4, 1,9101.'Said devices inlude a .Cluwh time?. 99,19.-

Said shaftis' adapted to slide through the hub 32 and is normally pressed outwardby a coi-ledL spring (not shown) contained in a barrel 38 iixe'd to; hub32." Thefrib 3510i the ratchet Wheel 31 bears rotatably on said hub`32and is under-v cut to bear also on-a plate 39 which is secured to" 'Saidhub bythe screvv's '30 that pass through therhub' 32 and arethreadedintothe ears 29. vPreferably the innerends oft' Athescrewsrreceiv'e' lor coperate with check nutsY Orrdevlces 40 forholding,r or locking them in lace.y VNormally the" clutch men'ilbers 34Old the `ratchet Wheel 31 in fixed relationship with the sleeve 23 andthe platen section 16'so' that line'spacing movement communicated to theWheel '31- 'bytheusualline y sp'acingdevices ofthe machina-Wilbe transfimitted-'to' the lplaten 16.
